You can easily calibrate a sensor using the Raspberry Pi using our calibration script. It runs from the command line using Blinka. This page assumes you have already set up Blinka on the Raspberry Pi, but if not, be sure to follow our CircuitPython on Linux and Raspberry Pi guide.
The easiest way to connect a 9-DoF sensor to the Raspberry Pi is to use a STEMMA QT/Qwiic connector which many of our sensors include.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
The Adafruit SensorLab – Magnetometer Calibration guide has been updated to include calibration instructions for the 9-DoF sensors using Raspberry Pi. Now you have an easy method for calibrating your 9-DoF sensors.
